Customizable In-Line Vacuum Potting Equipment for Automotive Tier1 Electronic Suppliers
HY customizable in-line vacuum potting machine targets diversified bubble-free encapsulation demands of global automotive Tier1 power & sensor electronic suppliers. Clients can freely configure glue mixing ratio, single/triple vacuum chamber, conveyor width, single/dual dispensing valves and constant temperature tank capacity based on actual workpiece outline and viscosity characteristics. The equipment reserves Ethernet communication port to synchronize vacuum degree, glue ratio and single-tray potting volume data with factory ERP via MES system. Compact semi-auto bench and full long inline production versions are both available for different production scale demands.
Full-Automatic In-Line Vacuum Potting Machine for EV BMS Module Bubble-Free Encapsulation
HY full-automatic in-line vacuum potting machine is customized for mass void-free encapsulation of new energy vehicle BMS high-voltage modules. It integrates independent A&B constant temperature stirring tanks, servo closed-loop proportional mixing unit, triple vacuum chamber continuous conveyor and built-in 3-axis vacuum gantry dispensing system. Real-time vacuum & glue weight dual sensors monitor working status, each workpiece tray binds exclusive QR code to store all potting parameters in MES system. Interlock alarm intercepts unqualified battery boards caused by abnormal vacuum value or uneven mixing ratio on-site.
Different from offline single-chamber vacuum dispensers on the market, HY modular in-line continuous structure completes feeding, vacuumizing, potting and discharging in one connected flow without manual workpiece transfer. All vacuum potting control standards comply with automotive IATF16949 specifications, compatible with PU, epoxy and silicone two-component adhesives synchronous production. We deliver 72-hour full machine aging test before shipment and provide one-stop overseas installation, debugging and operator training service. Quick program switching completes product model replacement within 12 minutes, greatly reducing downtime caused by frequent new power module iteration of auto electronic suppliers.

Fields of Application


- New Energy Vehicle Power Battery & BMS Module Encapsulation
For mass vacuum potting of EV BMS high-voltage boards and battery management modules. Triple independent vacuum chambers shorten cycle time, servo proportional system stabilizes AB glue ratio to eliminate internal voids. MES records vacuum degree & glue volume per tray to meet OEM IATF16949 batch audit standards.
- Automotive ECU & Sensor Electronic Control Unit Sealing
Tailored for Tier1 auto electronic suppliers’ controller encapsulation. In-line conveyor connects front assembly stations, built-in 3-axis gantry adapts irregular deep-cavity sensor housings. Full negative-pressure potting avoids air trapping to guarantee insulation & waterproof performance.
- Industrial Inverter & Transformer Coil Encapsulation
For medium & high-power inverter, transformer and motor coil vacuum potting. Large-volume heating tanks prevent high-viscosity epoxy precipitation, adjustable multi-stage vacuum parameters suit dense winding coil structures to eliminate tiny micro-bubbles.
- New Energy Commercial Vehicle On-Board Charger Encapsulation
Heavy-duty in-line vacuum potting version for truck on-board charger modules. Wide conveyor adapts large-size power assemblies, thermal cycle test matching commercial vehicle wide-temperature working environment after bubble-free encapsulation.
- Aftermarket Modified Electronic Small-Batch Potting
Compact semi-automatic bench in-line pilot machine for modification factories. Low investment, fast program switching for customized small power supply and sensor prototype small-batch encapsulation.
Core product advantages
Discover the difference that premium engineering makes with Huayu’s HY-SAV400-55L inline vacuum potting machine. Every detail is crafted for durability and performance — from the high-vacuum sealed chamber designed for years of reliable service to the precision drive system powered by servo motors and ball screws. The robust 840kg construction ensures stable operation at full capacity, while the anti-curing system and automatic glue refill protect your production from unexpected downtime. Configurable with multiple pump options, tank sizes from 15L to 55L, and optional upgrades like CCD vision and plasma cleaning, this is a machine that adapts to your evolving needs — quality that lasts, performance that grows.
Step into a new era of encapsulation excellence with Huayu’s HY-SAV400-55L vacuum potting solution. Unlike conventional atmospheric dispensing that leaves trapped air behind, our vacuum chamber technology ensures complete bubble-free potting for critical electronic components. The deep -98KPa vacuum environment allows glue to penetrate every corner of complex geometries, creating a dense, uniform seal that boosts waterproofing from IP67 to IP68 and doubles salt spray resistance to 1,000 hours. With 1~4 multi-head dispensing and configurable gear, screw, or piston pump options, this inline system adapts to epoxy, silicone, and polyurethane materials with unmatched versatility. Setting new benchmarks in precision potting technology.
Transform your production economics with Huayu’s HY-SAV400-55L inline vacuum potting machine. By automating the entire potting process with conveyor-fed inline operation, this system boosts productivity by 3–5 times compared to manual or semi-automatic methods. A single machine replaces 5–6 skilled operators while maintaining consistent 24/7 output. The precision vacuum process reduces material waste by up to 30% and cuts rework rates dramatically by eliminating bubble-related defects. With overall equipment efficiency reaching 95% and glue utilization above 98%, every hour of operation delivers measurable returns. Compact design, low maintenance, and rapid ROI make this the smart choice for high-volume electronics manufacturing.
Advanced vacuum potting technology shouldn’t be complicated to operate — and with the HY-SAV400-55L from Huayu, it isn’t. The intuitive WIN10/PLC+PC control system features a user-friendly interface that puts all critical parameters at your fingertips. Operators can quickly set up recipes, adjust mixing ratios from 10:1 to 1:1, and monitor production status in real time with minimal training. The inline conveyor design makes loading and unloading straightforward, and the observation window provides clear visibility of the vacuum potting process. Weighing 840kg with a sturdy, compact frame, this machine brings industrial-grade vacuum potting capability to your facility without requiring specialized expertise — simplicity that performs.
